(Repost for missing audio) Comparing offshore wind in China and Norway - with Erlend Ek
Environment China
Dear listeners, we hope you missed us during the long summer break! Now, we're back, and hope you'll join us again for another in-depth episode dealing with a rapidly expanding element of China's energy transition: offshore wind. Today, we’re talking about China’s offshore wind sector and how it compares to the strategies pursued by Western countries, typified perhaps by the example of Norway. Our guest is longtime Beijing Energy Network member Erlend Ek, who was posted to Beijing and lived in China for over 15 years. He is now senior research strategy and energy lead with China...

Emergency Podcast! Sunnylands Declaration and COP28 - with Li Shuo
Environment China
This is an emergency podcast about the Sunnylands Statement on Enhancing Cooperation to Address the Climate Crisis, which was released just a day ago. Top US and China climate negotiators Xie Zhenhua and John Kerry have held several days of talks at the Sunnylands estate near Palm Springs in California, and released this joint US-China statement in the lead-up to COP28 in Dubai. Just a few months ago, Kerry had visited BJ to negotiate similar topics, and President Xi had used the occasion to emphasize that China would set its own path on climate, and not give in to pressure. So this joint...
info_outlineToday we will be talking about China’s efforts to phase out hydrofluorocarbons (HFCS), a class of refrigerant with huge impacts on the climate. Our guest today is an expert on the topic, Prof Hu Jianxin. Professor Hu holds bachelor's and masters degrees in Chemistry from Peking University. He has been on the faculty at Peking University since 1986, and is currently professor at the College of Environmental Sciences and Engineering, Peking University, and also the Institute of Carbon Neutrality, Peking University. He has published numerous academic studies of HFCs, focusing on potential emissions reductions pathways as well as the cost of mitigation in various sectors. He was involved in the negotiations leading up to the Kigali Amendment as well as several other international agreements.
Topics addressed in this episode:
- How Prof Hu got started investigating HFCs
- Who needs to take action to reduce emissions of HFCs: chemical manufacturers, equipment manufacturers, consumers and repair/maintenance industry
- Near-term strategies for reducing and recycling HFCs
- Substitutes for HFCs (HFOs) - their costs, efficiencies, and timelines
- What does it mean when your air conditioner breaks and the repair person says you need more refrigerant

Some useful acronyms:
HFCs: Hydrofluorocarbons (replacement for CFCs but a dangerous greenhouse gas and hence targeted for reduction under the Kigali Amendment)
HCFCs: hydrochlorofluorocarbons (an ozone-depleting refrigerant)
CFCs: Chlorofluorocarbons (ozone-depleting refrigerant phased out by the original Montreal Protocol)
HFOs: Hydrofluoolefins (current and future substitute for HFCs)
UNEP: United Nations Environment Programme, pronounced "you-nep"
